for some reason my first tweet never posted, so I’ll try again.
Is there a way I can include the Raven Queen, a 4e deity, into a 5e setting? I want to make a deep gnome cleric of the Raven Queen We talk about her in the upcoming Mordenkainen's Tome of Foes. I'd consider using the Grave domain from Xanathar's or the Knowledge of Life domain from the PHB.
